Description

Technical Field

[0001] This utility model relates to the field of mold material discharge technology, specifically a foaming mold material discharge device. Background Technology

[0002] Existing devices using foaming molds require the foaming resin to be directly filled into the mold during operation, allowing it to melt upon heating and form a gas-liquid saturated solution. After further reaction, the foamed plastic part is formed. However, residual surface heat remains after molding, making it inconvenient to handle. Furthermore, during injection molding, the upper and lower molds are affected by the temperature of the injection liquid, which transfers heat to the upper and lower molds upon contact. Therefore, a demolding device is needed to assist in demolding the upper and lower molds, thereby reducing the temperature of the molds themselves and facilitating demolding. Thus, a foaming mold discharge device that solves the above problems is needed. Utility Model Content

[0003] In view of the shortcomings of the prior art, this utility model provides a foaming mold discharge device, which solves the problems mentioned in the background.

[0004] This utility model provides the following technical solution: a foaming mold discharge device, comprising: a processing table, a support column fixedly connected to the bottom of the processing table, a base placed on the outer wall of the processing table, a lower mold provided on the top of the base, a water inlet pipe connected to the outer wall of the lower mold, a water outlet pipe connected to the outer wall of the lower mold, a cooling circuit opened in the inner cavity of the lower mold, an injection groove opened in the outer wall of the lower mold, a support frame fixedly connected to the outer wall of the processing table, a lifting motor installed on the outer wall of the support frame, a lifting cylinder connected to the outer wall of the lifting motor, an upper mold connected to the bottom of the lifting cylinder, a high-temperature injection molding machine installed on the outer wall of the upper mold, a liquid tank opened in the inner wall of the upper mold, a diversion groove opened at the bottom of the upper mold, and a pneumatic connector installed on the outer wall of the upper mold.

[0005] Preferably, the lower mold is connected to an inlet pipe and an outlet pipe on both sides, and the outlet pipe is arranged opposite to the inlet pipe on the other side.

[0006] Preferably, the injection groove is simultaneously formed on the outer walls of both the lower mold and the upper mold, and the lower mold and the upper mold overlap to form a complete injection groove.

[0007] Preferably, the inner wall diameter of the cooling circuit is larger than the outer wall diameter of the injection molding tank, and the inner cavity of the injection molding tank is filled with foamed material.

[0008] Preferably, the outer wall of the lifting motor is connected to a lifting cylinder, and the length of the lifting cylinder is extendable.

[0009] Preferably, the liquid tank is connected to the inner cavity of the diversion tank, and the diversion tank is connected to the inner cavity of the injection molding tank in a vertical line manner.

[0010] Preferably, the outer wall of the high-temperature injection molding machine is provided with a material hopper, and the foaming material is melted at high temperature in the inner cavity of the high-temperature injection molding machine.

[0011] Preferably, the inner wall of the upper mold is provided with an air blowing port, and the opening of the air blowing port is set as an inclined opening.

[0012] Compared with the prior art, the present invention has the following beneficial effects: 1. This foaming mold discharge device, through the setting of water inlet pipe, water outlet pipe, cooling circuit, lower mold, upper mold, etc., allows the lower mold and upper mold on the device to overlap and use the injection tank on the device to perform product injection. This causes the temperature of the upper and lower parts of the lower mold and upper mold to rise during injection. The water inlet pipe and water outlet pipe on both sides of the device, together with the cooling circuit, form a cooling water flow channel. As a result, the heat squeezed in the inner cavity of the lower mold and upper mold is reduced by the cooling water flowing in the inner cavity of the cooling circuit. At this time, the contact area between the lower mold and upper mold and the inner and outer walls of the molded foamed product will gradually accelerate the separation from the mold due to the temperature difference of the contact surface.

[0013] 2. This foaming mold discharge device, by setting up a pneumatic connector, air blowing port, lower mold, injection tank, etc., allows the upper mold on the device to rise upward under the drive of the lifting motor and lifting cylinder, leaving the injection-molded foamed product in the injection tank of the lower mold cavity. The device is connected to an external pneumatic device through the pneumatic connector, so that the pneumatic connector on the device blows cold air to the surface of the lower mold at the bottom through the air blowing port, thereby lowering the foamed product in the lower mold cavity again, making it easier to pick up and avoiding the situation where the temperature of the molded foamed product cannot reach the conditions for picking up.

Detailed Implementation

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] Please see Figure 1-5 A foaming mold discharge device includes: a processing table 1, a support column 2 fixedly connected to the bottom of the processing table 1, a base 3 placed on the outer wall of the processing table 1, a lower mold 4 provided on the top of the base 3, a water inlet pipe 5 connected to the outer wall of the lower mold 4, a water outlet pipe 6 connected to the outer wall of the lower mold 4, a cooling circuit 7 opened in the inner cavity of the lower mold 4, an injection groove 8 opened on the outer wall of the lower mold 4, a support frame 9 fixedly connected to the outer wall of the processing table 1, a lifting motor 10 installed on the outer wall of the support frame 9, a lifting cylinder 11 connected to the outer wall of the lifting motor 10, an upper mold 12 connected to the bottom of the lifting cylinder 11, a high-temperature injection molding machine 13 installed on the outer wall of the upper mold 12, a liquid tank 14 opened on the inner wall of the upper mold 12, a diversion groove 15 opened at the bottom of the upper mold 12, and a pneumatic connector 16 installed on the outer wall of the upper mold 12.

[0018] The lower mold 4 is connected to an inlet pipe 5 and an outlet pipe 6 on both sides, with the outlet pipe 6 positioned opposite to the inlet pipe 5. Cooling water is supplied to the inner cavity of the lower mold 4 through the inlet pipe 5, allowing the cooling water to flow through the inner cavity of the lower mold 4 and toward the outlet pipe 6 on the other side of the device. This allows the overall temperature of the lower mold 4 to diffuse outward from the inner cavity of the lower mold 4 as the cooling water passes through the inner cavity of the lower mold 4, thus cooling the temperature.

[0019] The injection groove 8 is simultaneously opened on the outer wall of the lower mold 4 and the upper mold 12, and the lower mold 4 and the upper mold 12 overlap to form a complete injection groove 8. When the upper mold 12 on the device covers the top of the lower mold 4, the product is formed in the inner cavity of the injection groove 8 by the injection molding process. Thus, the injection groove 8 on the device is divided into upper and lower sides by the lower mold 4 and the upper mold 12, and the injection molding work is carried out by the injection grooves 8 on the upper and lower sides.

[0020] The inner diameter of the cooling circuit 7 is larger than the outer diameter of the injection tank 8. The inner cavity of the injection tank 8 is filled with foamed material. When the foamed material is filled into the inner cavity of the injection tank 8, the temperature of the lower mold 4 and the upper mold 12 on the device gradually increases due to the foamed material inside. The temperature at the center of the lower mold 4 and the upper mold 12 also increases. As a result, the cooling circuit 7 on the device is arranged around the outer wall of the injection tank 8. When the cooling water flows from the inner cavity of the cooling circuit 7, it cools the lower mold 4 and the upper mold 12 internally.

[0021] The outer wall of the lifting motor 10 is connected to a lifting cylinder 11, and the length of the lifting cylinder 11 is telescopic. When the lifting motor 10 on the device outputs telescopic power, the lifting motor 10 on the device can control the lifting cylinder 11 to telescopically extend and retract, and use the lifting cylinder 11 on the device to drive the upper mold 12 to lift and lower in height, so that the upper mold 12 on the device can actively overlap and separate from the lower mold 4 directly above it.

[0022] The liquid tank 14 is connected to the inner cavity of the diversion tank 15, and the diversion tank 15 is connected to the inner cavity of the injection molding tank 8 in a vertical manner. Through the connection between the inner cavity of the liquid tank 14 and the diversion tank 15, the liquid material delivered from the liquid tank 14 is diverted to the inner cavity of the injection molding tank 8 through the three vertical diversion tanks 15, thereby filling the inner cavity of the injection molding tank 8.

[0023] The high-temperature injection molding machine 13 has a material hopper on its outer wall. The foamed material is melted at high temperature in the inner cavity of the high-temperature injection molding machine 13. When the foamed material is filled by the material hopper on the surface of the high-temperature injection molding machine 13, the high-temperature injection molding machine 13 heats the material at high temperature. Then, the high-temperature injection molding machine 13 delivers the injection liquid material to the inner cavity of the liquid tank 14, so that the liquid material flows through the liquid tank 14 into the inner cavity of the diversion tank 15.

[0024] The upper mold 12 has an air inlet 17 on its inner wall, and the opening of the air inlet 17 is set as an inclined opening. There are four air inlets 17 on the device, so that the four air inlets 17 on the device are symmetrically arranged in the inner wall of the upper mold 12, and the openings at the bottom of the symmetrical air inlets 17 are all set as inclined openings towards the middle position. When the pneumatic connector 16 on the device delivers cooling air to the air inlet 17, the air inlet 17 on the device can cool the injection tank 8 in the inner cavity of the lower mold 4.

[0025] The working principle involves first setting up a structure including a water inlet pipe 5, a water outlet pipe 6, a cooling circuit 7, a lower mold 4, and an upper mold 12. When the lower mold 4 and upper mold 12 overlap, the product is injected using the injection tank 8. During injection, the upper and lower parts of the lower mold 4 and upper mold 12 heat up. The water inlet pipe 5 and water outlet pipe 6 on both sides of the device, in conjunction with the cooling circuit 7, create a cooling water flow channel. This allows the heat generated inside the lower mold 4 and upper mold 12 to decrease in temperature as the cooling water flows through the cooling circuit 7. At this point, the lower mold 4 and upper mold 12 mold the foamed product. The contact area between the inner and outer walls will gradually detach from the mold due to the temperature mismatch at the contact surfaces. By setting up structures such as pneumatic connector 16, air blowing port 17, lower mold 4, and injection tank 8, the upper mold 12 on the device is raised upward under the drive of lifting motor 10 and lifting cylinder 11, leaving the injection-molded foamed product in the injection tank 8 inside the lower mold 4. A pneumatic device is connected to the pneumatic connector 16 on the device, so that the pneumatic connector 16 blows cold air onto the surface of the lower mold 4 at the bottom through the air blowing port 17, thereby lowering the foamed product inside the lower mold 4 again, making it easier to pick up and avoiding the situation where the temperature of the molded foamed product cannot reach the conditions for picking up.

[0026] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
